RULING-MACHINE.

SPECIFICATION formingpart of Letters Patent N 0. 674,434, dated May 21,1 901.

Application filed October 30, 1899. Serial No. 735,200- (No model.)

To a whom, it may concern:

Be it known that I, CHARLES BURROWS, a citizen of the United States, anda resident of the city and county of Schenectady, in the State of NewYork, have invented certain new and useful Improvements inRuling-Machines, of which the following is a specification.

My invention relates to improvements in ruling-machines shown anddescribed in Letters Patent Nos. 568,235 and 568,236, datedSeptember22,1896; and it consists in the devices and parts andcombinations of devices and elements hereinafter described, and setforth in the claims.

The objects of myinvention are to provide in a ruling-machine and incombination with a pen-beam provided with ruling devices and adapted tobe raised and lowered at pleasure of an operator for convenience ofadjusting the said ruling devices a vertically-moving bed which isautomatically operated for carrying sheets of-paper to the pen or pensof the machine and withdraw the same therefrom at times and intervals asmay be required by the character and kind of ruling to be given to thesheets, and also to provide mechanism by which the sheet-supporting bedmay be automatically raised, so as to carry a sheet to be ruled up tothe pens, and there be held for a proper time and then be automaticallylowered for carrying the sheet out of contact with the said pens orinking-rollers and be so held for such a time as may be required beforebeing moved up toward the pens for receiving ink therefrom when theruling is to be resumed, and, further, to remedy the defects arisingfrom a trembling of the pens or slight movements of the points of thesame, which to a degree attended the same when dropped down on the paperas heretofore when operated by the pen-beam and dropping from a raisedposition to the paper and checked as heretofore, so as to give to thepen-beam a shock which generally caused a quivering of the pens.

Other objects and advantages of this invention will be fully understoodfrom the follow--' ing description and claims when taken in connectionwith the annexed drawings, in which- Figure l is a side elevation of aruling-machine embodying my improvements with so much of said machineand parts and devices thereof as is necessary to show the connection ofthe cooperating parts and devices with the improvements in thisinvention. Fig. 2 is a plan view of the same.

Similar letters of reference refer to similar parts throughout bothviews.

In the drawings, A is the drive-shaft of the machine. A is a feed-rollermounted on said shaft, and ais the usual endless cloth carried bysuitable rollers for carrying the sheets to be ruled. O is a revolvingdisk secured on shaft 0 and carrying movable cams O and G which areadjustable at will on the peripheral portion of said disk. Themechanisms for gearing these above-mentioned parts together so that thesaid revolving disk and its adjustable cams may be properly revolved bythe said drive-shaft are fully shown and described in my Letters PatentNo. 568,235, above mentioned, and therefore unnecessary to be shown anddescribed in this specification.

B is the pen-beam, arranged across the machine and supported from eachend from the side rails of the frame of the machine by standards D, (oneof which is shown in the drawings) which are adjustable and are fullyshown and described in my Letters Patent No. 568,236, above mentioned,and therefore unnecessary to be more particularly described. Thispen-beam B is supported from standards D by means of a horizontal pintle(1, provided at each end of the said beam and working, respectively, ina suitable bearingpiece d, secured therewith with one of said pintles asshown in Fig. 2, provided with screw-threads (1 working in ascrew-threaded split nut D, provided with tightening-screw d and havinga horizontal arm cl working in sleeve D which is longitudinally splitand tightened by screw d and is provided with vertical stem D which isadjustable at will in said standard D. This pen-beam is also provided atone end with arm B, which is pivoted by pivot 12 on the upper side ofsaid pen-beam and is adapted to be variously adjusted in verticaldirection by means of screws b 12 so that its free end I) may bedepressed or elevated in relation to a suitable stationary toward and tothe pens b and downwardly.

and away from said pens at times and intervals as the character and kindof ruling of sheets of paper may require, and'any suit able mechanismarranged between said vertically-moving bed E and the revolving disk 0and adapted to be operated by cams C and C may be employed for movingsaid bed toward the pens b and holding the sheets supported thereon incontact with the said pens and for effecting a lowering of said bed.that the sheets may be carried out of contact with the same. Thisvertically-moving bed E may be of any suitable material, as of metal orwood, or both combined, as may be preferred, and be made with anysuitable length and width to adapt it for service in the machine forsupporting sheets of sizes to be ruled. It is supported from the siderails of the frame of the machine o'rany stationary piece securedthereto by arms F, one at each end of the bed. Only one of these arms isshown in the drawings, as each arm is a duplicate of the other and adescription of one will suflice for the other. The forward end portionfof the arm F is secured, by means of bolts or screws 6 e, to the saidbed, preferably by being applied to the end of the same, and its rearend portion f is pivoted to the side rails D (one of said rails only isshown) by a suitable pivot F. The forward end of each said arm isprovided with an outwardly-projected horizontal flange F preferablyintegral with portionfof said arin, as shown in Fig. '2.

G is a editable rock-shaft extending from one side of the machine to theother and supported from the end journals in suitable bearings G, (oneonly shown,) provided with the.siderai ls D, to which they are securedfrom their upper sides. With these hearings G are provided a lugg,having a screw-threaded hole 9', (indicated by dotted lines in Fig.1,) which receives the adj ustingscrew Gr (shown in Fig. 1) to beprovided with jamnu'tg Rigidly secured to each end of the rockshaft G,at near the forward end of the bedsupporting arms F and beneath theflange F are arms H, integral with suitable hubs h, which arms are eacha duplicate of the other and of which one arm H only is shown by fulllines in Fig. 1 and indicated by full and dotted lines in Fig. 2.Secured to the rocks'haft G at a point opposite the periphery of therevolving disk 0 is the pendent arm J, integral with hubj, by which itis secured to shaft G. The lower end of this pendent arm is preferablyprovided with friction-roller J,

which is about opposite said periphery. Secured to the same end ofrock-shaft G and adjoining the pendent arm J is the gage-arm K andkeeper-arm L, both of which are preferably integral with hub it, bywhich they are secured to the rock -shaft. 'These several arms H, J, K,and L are so secured to the rock-shaft G that they may move with thesame and also so that when either one of the same is moved by itsoperating mechanism provided the other arms will be correspondinglymoved, as will be hereinafter described.

Secured to the side rail D and in part opposite the revolving disk 0 isthe latch-frame M, provided with latch N, pivoted to the former andhaving at its rear side a reacting spring M, (indicated by dotted linesin Fig. 1,) all similar to the latch and frame and reacting spring shownand described in my Patent No. 568,285 before'mentioued. N is providedon its outer side with the inclined project-ion P, which is situated inthe length of the latch, so as to be in the line of the circle in whichthe latch-operating cam 0 (shown in the drawings) is carried by therevolving'disk O. This latch is also provided with stop Q. (Shown byfull lines in Fig. l and indicated by dotted lines in Fig. 2.) When inthe revolution of disk 0 the cam C is carried inwardly in direction fromthe inner side of said disk, the keeper-arm L will by the weight of thevertical moving bed E and its pivoted arms F, imposed on arms H, movesaid am L'to the front of Stop@ at the instant the "latch N is movedinward by the act-ion ol cam C on the projection P, and arms H will belowered and gage-arm K will be raised to dotted lines and strike againstthe lower end or the adjustin-gscr'ew G which limits the drop of thesaid arms H, and consequently that of the bed E, from the penis I), andso long as the keeper-arm L is in front of the said step Q the said bedwill be down and out of contact with said ruling devices and all thesaid arms will be'in position of dotted lines, indicating their changedpositions. When in the revolution of the revolving'disk G the adjustablecam 0 which is shown in Fig. l to be projected beyond the periphery ofsaid disk, is carried'against frictio'n-roller J ,pivotedonthe pendentarm J ,said arm J will be moved back from dotted lines in Fig. 1 to thatof full lines and so turn the rock-shaft that it will carry the gage-armK to full lines and away from the adjusting screw and arms H upwardly,so as to move the bed E u p, so as to carry the paper thereonintocontact with the pens b, which latter is so well known as not torequire any particular description. When said arms J, K, and H have beenso moved to full lines, the keeperarin L'will have been moved fromposition in front of stop Q and from pressing in said latchthro'ugh's'aid step Q, and its front side edge will be brought to therear side of said stopjwhen the reacting spring M will push This latchthe latch forward and carry said stop Q in engagement with saidkeeper-arm L, and thereby lock the rock-shaft from moving and thepaper-supporting bed in raised position, as shown.

The drawings show by full and dotted lines two similar adjustable cams Cand two similar adjustable cams C secured to the rim of disk 0, theformer for operating with the inclined projection on the latch N and thelatter for actuating arm L on the rock-shaft. These cams C C may be eachused in number of one or more, as may be required, and may be variouslyset and adjusted at pleasure on the rim of the disk as may be necessaryas the ruled ink-lines to be produced on the paper supported on the bedmay require for length, continuity, beginning, and stopping of the same.

The gate for regulating the feed of sheets of paper and tapes forcarrying the same beneath the ink-ruling pens or rollers and otherdevices employed in rulingmachines are omitted from the drawings andthis description, as they do not form any part of this invention, andthese devices and mechanisms in my preferred form are clearly shown anddescribed in my patents above mentioned and therefore do not require anyfurther description. It is to be understood that the movable bed-piecemay be variously changed or modified in its form of construction andproportions and that it may have its rearward portion supported invarious ways Without changing or aifecting its operation or that ofparts and devices employed with said bed in this invention.

My above-described improvements operate to allow the ruling devicescarried by the penbeam to be readily and nicely adjusted in relation tothe paper to be ruled, so that a suitable contact of the former with thelatter may be had without any imposition of an excess of pressure of theruling devices on the paper over that required to mark, the same andalso operate to remove the cause of trembling of the ruling devicesarising from shocks heretofore attending the sudden stoppage of the dropof the pen-beam carrying the said ruling devices, which shocks weregenerally eonsequent from the jar communicated to the pen-beam from thestriker or striker-bar heretofore employed when that device falls inplace on the rest which is provided to stop the fall of said striker orstriker-bar.
